DNA-dependent ATPase. May modulate chromosome segregation. Interacts with UBR1 and UBR2. Interacts with MCM10; this interaction regulates RECQL4 unwinding activity. Up-regulated in actively dividing cells. Ubiquitously expressed, with highest levels in thymus and testis. Belongs to the helicase family. RecQ subfamily. Note: This description may include information from UniProtKB.
